Hi again,
I just updated to 2.12.2 as I was having a problem with events saving and updated in a panic without remembering this. Now all my days are highlighted again and when I tried to reinstall this, it said there was a version mismatch as it's only for 1.10. Is there any way to still use it on the new one? Any feedback would be greatly appreciated!

You're too good Thanks so much, that's working perfect (and I see it adds a different colour to the hover text too which is handy). The issue with the events being added I was having earlier seems ok now too! Thanks again, really appreciate it!
